Han Solo and his cousin Thrackan Sal-Solo were both thought to be Berethron's descendants. In 8 ABY, C-3PO invoked that lineage to prove Solo's worthiness to marry Leia Organa before the Hapan Royal House. Han's great-grandfather, Korol Solo, was a presumed descendant of Berethron, and used that to put a forward a claim as pretender to the throne of the Corellian Empire, but was hanged for his crimes.
